Arana Taumata had been on a lunchtime walk in Brisbane when he came across a woman who had been knocked down.
The woman's death comes as storms rip through parts of Queensland.
2018's Cyclone Owen led to authorities issuing croc warnings across North Queensland.
The fisherman was bitten three times before he escaped.
"They started preparing for the end of days."
“The welts were just everywhere. It looked like she’d been whipped."
He was found just 3km from his car, suffering from exposure to the elements.
